EUGENE a PAULDINE ATTORNEY 3,135,269 CURLING IRON HAVING DETACHABLE CURLING TUBE Eugene E. Pauldine, 12 Main St., Cortiand,'N.Y.

Filed June 1, 1962, Ser. No. 199,344 12 Claims. (Cl. 132-33) This invention relates to novel cosmetic devices for producing curls and waves in hair, and especially to devices of the kind which are capable of producing waves United States Patent and curls of diiferent sizes, and which result in rapidly acquired and pleasing effects in hair styling; and to such devices of simple construction which are economical to manufacture and comprise ready means for effecting rapid alterations therein whereby diiferent sizes and characters of waves are made possible.

Heretoford'it was common practice in the art of arranging and styling hair to separate the hair on the subjects head into locks, moistenthe locks and wind each one on a separateroller of selected size, where the locks were fastened in this condition until they were dried. The drying could be done under prevailing atmospheric conditions, or could be hastened by means of hair driers which blew heated air on the subjects head. The time required to carry out such a process is undesirably long and inconvenient. Rolling and securing the separate locks of hair on the many rollers for drying is a meticulous operation involving some inconvenience and often requiring the services of a skilled operator. The storing of the large number of rollers or curlers required was a considerable inconvenience. Resultantly, the need has long been recognized for devices which will make hair styling more convenientor less time consuming, both to the specialized stylist and to the subject worked upon.

It is among the objects of this inventiontoprovide improved devices which will facilitate the process of creating enlarged and varied sizes of curls, rolls and waves in hair.

Another object is to provide devices comprising a small number'of separate parts. 7

A further object is to provide devices which will shorten the time required to carry out the process.

Another object is to provide devices which are readily self-operable by the person whose hair is being styled, and which may be used without undue discomfort to the operator.

Another object is to provide novel means for rapidly mounting different sized interchangeable tubes or curlers on a heat emitting support, and for positively retaining ,a mounted tube thereon without relative angular or endwise displacement while the operation of winding 'and curling the hair on the tube is being carried out. Still other objects of the invention will become apparent from the following description of devices illustrating the best manner presently contemplated of practicing the invention. j

In general devices made in accordance with the invention comprise an elongated heat emitting element, such as a round hollow rod which is desirably, but not necessarily heated 'by an electrically energized heating coil" tubes'having' cross sections of circles, ovals or ellipses, are adapted to be removably mounted on the heat emitting element one at a time, as the operative curling elements upon which a lock of hair is wound or rolled to be curled. A mandible is provided to bear on the outer surface of the tube for holding the ends of the lock of hairwhile it is being wound on the tube and over the mandible. Means are provided on each curler tube for tn fiuntin'g the same on the heat emitting rod, and such means providesfor impressing the rod on the inner surface of the tube, or upon a heat transfer member therewithin. -Means are also provided for avoiding angular displacement of the heating element with respect to the curler tube in at least one direction, and preferably in either direction. Means for preventing or restraining endwise displacement of the heating element and curler tube with respect to each other is provided.

The mandible support and handle of the device are combined with the heating element so that they will not became a'ng'ularly or linearly displaced with respect to each other when in operative position. Such a combinatior'l 6f the mandible support, handle and heat emitting "rod may be made by any of the means for such purposes that are wellknown to the prior art of electric curling irons. The mandible and mandible support may comprise spring means for manipulating the mandible and impressing it upon the outer surface of the enlarged curler tube, and suitable means for this purpose are well known in the same prior art. a

More particularly, referring to FIG. 1, an elongated heat 'er' nitting element 1, such as the elongated cylindrical electrically heated rod of a hair curling iron is adapted to be connected 'to a source of cilrrent through the leads 2 and 3. A handle 4, a mandible mount 5 and the rod 1 are securely mounted together so that they will not move independently of each other, either axially or arcuately when in operative position. A finger or mandible 7 is 'h'ifigedly mounted on a hinge bolt '6 on the upper part of the mandible support so that the mandible will lay longitt'idinally in repose along the outer surface of a de "mountable, enlarged curler tube 8 which is demountably secured on the rod and operates as the curler. A depressor is provided to press the mandible 7 on the tube 8 :suffic ientlytohold the ends of a lock of hair While rolling the same on the curler tube 8. A convenient form of depressor comprises the elevated depressor bar 10 which isla n extension of the mandible and extends toward the handle '4 from the hinge 6. The depressor may be operated to raise the mandible by pressing the end thereof downwardly; but other forms of depressors may be 'used. spring "11 is biased to press the mandible on the tube 8, and 'in' the form shown a pin 12 anchors one end of the spring 11 to the handle.

are provided to render the curler tube 8 den'rountable so that it may be replaced by curler tubes of other diameters. Preferably the heat emitting element 1 -is compressed longitudinally along the inner surface of the tube 8 to provide good heat transfer from the element 1 to the tube, as illustrated for example in FIGS.

greater contact surface along the inner surface of the tube which is interposed between the heated rod 1 and the inner surface of the tube, as illustrated in FIG. 2.

A plurality of units 13 may be used. Among the devices for pressing the heat emitting element 1 against the inner surface of'the tube 8 are resilient receptacles which may also serve as positioning receptacles, such as those illustrated in FIG S. 5, 6, 8 to 10 and 13 to 20. A resilient compressing and positioning means may also be combined with a fixed locking device which positively locks or restrains the rod from arcuate displacement, as illustratedin FIGS. 3 and 4, in which either or both of these means may be mounted within or at the ends of the tube and spaced apart.

Other forms of resilient receptacles and mounting devices are illustrated in FIGS. 6, 8, and 13 to 20. The part 15 shown in FIG. 14 may be made by cutting a section of tube about the size of tube 8 and'pressing a section of the peripheral band inwardly to form a yoke or saddle within which the heating element is seated and retained from sidewise movement. The saddle serves to position and press the heat emitting rod 1 into direct heat conduc tive contact with thedinner surface of the tube. Such positioning and pressing members are preferably composed of relatively stiff resilient or spring-like material in the form of bands or wire. The bands may be narrow or wide and the Wire may be large or small, as convenience or necessity may demand. They are formed with the re-entrant saddle or yoke so that the heat emitting rod will be retained lengthwise of the curler tube and pressed against the inner surface of the tube and within the re-entrant part. The yoke or saddle is secured within the tube by the outward pressure of the band 15 or spring Wire against the tube, as illustrated in FIGS. 9 and 13 to 20, but supplemental anchoring means may be used, such as the connecting bar (FIG. 17) which connects the spaced saddle members 150, wherein a force tending to displace one of the members will be resisted by the others through the connecting rod 30. The re-entrant yoke or saddle is positioned directly under the mandible 7, At least three bearing points on the heating emitting element are provided in order to impress the rod firmly against the inner surface of the tube and retain the rod from sidewise displacement. Thus the rod is held in contact with the tube along a longitudinal line on the inner surface thereof, and at least two points of contact are provided in each yoke on opposite sides of a plane passing through the longitudinal line and the axis of the tube. A pair of mounting elements spaced from each other is desirable, but more may be used. Where the mounting element or receptacle is of considerable length, or where it approaches the length of the tube, as illustrated in FIGS. 13 and 19, only one receptacle may be used.

Besides the receptacle for mounting and impressing the heat emitting rod and tube together, means are provided for holding the heat emitting element 1 and curling tube 8 from endwise and angular displacement with respect to each other. For this purpose a notch 20, as illustrated in FIGS. 9, 10, 11 and 16 may be cut in the near end of tube 8, the same'being within the area centered by the line of contact between the heating element and the curling tube, and preferably in line with said line of contact. A key member, such as the pins 22, 23, 23a, 23b or 230 engages the margins ofthe notch and positively arrests relative angular movement. In modifications such as those illustrated in FIGS. 9, 13 to 16 and 18 to 20 where the mounting element is a band or septum within the tube, the engaging notch may be provided in the near end of the tube (FIG. 9) -or'in the yoke member. In all cases the key is desirably provided on rod 1 so that the longitudinal line of contact of'the rod within the tube (FIGS. 16 and 19) will be disposed under the center line of the externally mounted mandible. The margins of the notch 20 and fitting tongue or key operate as a lock and keyto prevent angumay be used to limit the advance of the rod in the tube and they will be referred to below. Various modificat'ions of this means may be provided, such as that of attaching the pin 23 directly to the heat emitting rod 1 (FIGS. 6, 10 and 16), or a male element 22' (FIG;

' in FIGS. 2 to 6 and other figures.

11') on the curler tube and a fitting notch 23a on the collar 21 may be it used. Still other modifications, such as that shown in FIG. 12 may be used, wherein the portion of the mandiblesupport 5 which extends around the heat emitting element 1 is lengthened forwardly and the tongue 22, or the notch 23a, is made a part thereof.

Other means for limiting the endwise movement of the heat emitting element and for locking the roller tube and heating rod from angular movement are illustrated Referring to FIGS. 2 to 4 the outer end portion of the heat emitting element 1 is made out-of-round, as for example by notching its far end. An abutting member 25 is attached to the far end of the roller, or near the end thereof, and a fitting out-of-round opening is formed for engaging the part 25. The female part may be formed to locate the rod in contact with the inner surface of the curler tube, as illustrated in FIG. 4, or it may be dis posed to retain the rod apart from the inner surface; In the latter case heat conducting elements 13 are mountin the near end of the septum, having regard to the proper ed within the tube and incontact with the rod for conducting heat from-the rod to the inner surface of the tube, of which any desired number may be used. As illustrated in- FIGS. 3 and 4, a septum 25 is mounted on theend' of the tube and the out-of-round opening is 'formed therein. A septum-'25 is attached to the near end of the tube and an opening is formed through which the rod is passed.

FIGS. 1, 7 and 9 to 12 illustrate a modified means for preventing angular displacement of the heating rod with respect to the curler tube. In such modifications a collar 21- is attached to or anchored around the heat emitting rod so that it will not be displaced. A tongue is provided on the far end of the collar to project into the notch 20 and the tongue 22a is provided to engage the sides of the mandible support 5 so that the collar will not turn or otherwise be displaced on the rod. The collar maybe shrunk upon or riveted to the rod. The collar and mandible support may be made of one piece 'as illustrated in FIG. 12in which the tongue 22 is formed. Alternatively the tongue may be provided on the tube and the notch on the collar.

FIG. 8 illustrates a modification of the device for mounting the curler tube on the heat emitting rod which comprises an elongated spring 18 mounted longitudinally within the curler tube 8 by means of a rivet 17 which passes through the tube wall, but other means of attachmerit may beused. The spring operates to press the heating rod forcibly along the inner surface of the tube and retain these elements in parallelism. The spring also retains the tube from relative endwise and arcuate displacement. A locking notch 20 may be additionally provided on the near end of the tube to engage a locking key.

FIGS. 8, 9 and 13 to 20 illustrate various forms of receptacles mounted within the curler tube, either as a continuous receptacle extending through the tube or as several members, positioned throughout much, or all of the length of the tube, or as narrow sections of such longer elements, of which two or more are provided. Of the latter type in which short sections, such as the narrow bands 15 and 16 (FIGS. 9 and 13 to 16) are used, a locking notoh may be provided in the near end of the tube or in the nearest receptacle" member 15, as illustrated in FIGS. 9, l5and 16.

FIG. 16 is illustrative of another form of yoke and a key for engaging a notch in the receptacle, thereby locating this functional element within the tube, rather than at one end thereof. In this modification the key 23c on the rod l engages a notch in the yoke 15 which is nearest the near end of the tube. In the wire form of yoke (FIG. 17) an undulation may be formed in the yoke at the near end. This undulation engages the key, and in modifications comprising septums, as illustrated in FIG. 20 the notch and pin 23c are formed location of the mandible as explained hereinabove.

The modification illustrated in FIGS. 17 and 18 comprises a locking device of the kind hereinabove described in which a projection 23 on the rod engages a notch in the near end of the tube, and a mounting device for the rod 1 comprises the somewhat S-shaped mountings 15c which are made of spring steel wire and disposed near the ends of the curler tube. The resilient yokes and compressing elements of this receptacle are joined by a longitudinally disposed bar or wire 30 which provides considerable additional stability tending to retain the elements in their intended positions and avoid long'itudinal displacement. A similar bar may be provided to combine the functions of the flattened encircling memhere 15 of FIGS. 14 and 15. The mount shown in FIGS. 17 and 18 may desirably be composed of a single length of tempered spring wire bent to the shape illustrated, so that the tail portions of the S-shapes will frictionally contact and press outwardly against the inner wall of the tube, and the longitudinally disposedbar 30 will also press'agai'n'st the tube along a longitudinal line between the spaced S-shaped members.

Referring to FIGS. 19, 20 and 21 the receptacle or yoke is constructed integrally with the tube, and formed by longitudinally disposed septums mounted therein. .The septums converge and are'spaced apart at their inner margins to form a narrow slot. This form of receptacle is. desirable in a curler tube composed of a metal or alloy which is capable of being extruded to form tubes, such as aluminum and some of its alloys, but such septums may be attached by other means. As illustrated in FIG. 19 the yoke or saddle is elongated and comprises septums extending from the inner surface of the tube. It comprises the spaced septums 35 and 36 which provide at least two of the three lines of contact along the heat emitting rod. By the process of extrusion the tube and this receptacle member may advantageously beiormed in one and the same operation, thus avoiding fabricating expense. The extruded tube is preferably made in long sections and then sub-divided into curler tubes of desired length, the septums running the full length of the tubes. An arrangement having three lines of contact is shown, in which the heat emitting rod is pressed against the inner wall of the tube along. a longitudinal line which constitutes one of the lines of contact that is disposed parallel to the center line of the mandible. A second line of contact is along a line in septum 35 which terminates at the point indicated by the dot 37, and the third I line of contact is in septum 36 along the line which terminates at the dot 38. The septums are arranged to converge and to provide a line of contact lengthwise of the tube underneath the mandible such that the rod will fit sufficiently snugly to prevent unintended endwise disengagement of the tube from the rod when mounted and in operation, and at the same time being sufficiently snug to permit intended assembling and dissassembling of the tube from the rod without .an undue use of force. It is intended that the tubes shall be capable of beinginterchanged readily and without the use of tools.

Assembly of the tube on the rod comprises inserting the rod endwise into the space 40 within the yoke formed by the converging septums or webs and along the lines of contact just described; Accordingly the lines of con- .tact terminated at. 37 and 38 are on opposite sides of a plane passing through the axes of the rod 1 and the tube 8. The septums 35 and 36 may be provided with rounded surfaceson the sides contacting the rod, thereby conforming more or less to the contour of the rod, as illustrated in FIGS. 20 and 22. This contouring may also be provided as the inner contacting surface of the tube, in which case it is evident that the added metal enveloping the rod constitutes an efiective heat transfer device, resembling in function the heat transfer device shown in FIG. 2. In the device shown in FIG. 22 it will be seen that a portion of the inner wall of tube 8 is also contoured to the surface of a portion of heating element 1,

. ing a slot 41 (FIG. 20) within which the pin 236 (FIG.

19) on the rod 1 is located so that the mandible '7 will extend along the outer surface of the tube in proper position. Thus where the slot 41 is situated in a radial position with respect to the tube, the pin 230 is placed along the rod 1, which will be in a plane normal to the tube surface area, which is embraced by the mandible and which passes through the longitudinal center line of the mandible, thereby providing means to prevent angular displacement of the rod with respect to the tube. The slot may be provided in a non-radial position, in which case the pin23c on the rod is positioned to engage the margins of the slot and dispose'the mandible opposite the line of contact along the rod and inner surface of the tube.

'In FIG. 20 the pin 230 is engaged in a notch in the near end of the septum 36 and functions additionally as a stop member to limit the travel of the rod within the tube in the manner that pin.23c operates in the notch in the near end of the yoke 15 of FIG. 16.

Any of the yokes of FIGS. 13 to 16 and 18 to 20 may be of any desired length, but not longer than the length of the tube. The narrower yoke, such as those of FIG. 9 being used in series according to the amount and nature of the support desired. The longer yokes may be used singly. The yoke shown inFIGS. 13 and 16 may be afiixed to the inner Wall of the tube by rivets as illustrated in FIG. 8, by welding as indicatedby the weld w in FIG. 13 or by other suitable means.

A desirable means for limiting the endwise travel of the rod 1 while mounting the same within the tube 8 as an .alternative to the abutting pin 23 of FIG. 17, 01'

230 of FIGS. 11 and 20,.comprises an abutment formed in the base of the mandrel which is illustrated in FIG. 21. The base portion 45 of the mandible is formed to extend downwardly and skirt the rod 1 sufficiently to permit a shoulder or abutment 46 to be formed therein by cutting away the metal. The shoulder 46 is disposed along the rod a distance which is sufficient to engage the near end of the tube 8 when the rod and curler tube are in operative position, as illustrated in FIG. 21. This abutting means is desirable as a simplified means for use in modifications employing receptacles illustrated in FIGS. 13 to 20, but as pointed out hereinabove other stop members may be used. This abutting means is especially desirable in combination with the yoke type receptacle and the key pins 230 located within the tubes for preventing angular movement of the rod, such as the combination illustrated in FIGS. 19 to 21.

Instead of circular tubes, out-of-round tubes of closed curvilinear cross section may be used, such as elliptical or ovate forms.

In operation a lock of hair to be curled is grasped by its ends between the mandible and the heated mounted tube of selected size. The lock is then rolled on the tube and over the mandible. Commonly the hair will have beenmoistened. After having been rolled on the heated roller it is retained there until the curl is sufiiciently set, say about twenty seconds. Then the curled hair is released from the roller. Where a different size of curl is desired on another part of the head, the tube is removed from the rod without cooling. This may be done by protecting the hand with a glove or towel and another curler of selected size is mounted on the rod.

The devices of the present invention provide means for producing a great variety of hair. styling effects by em ploying a single relatively costly heat emitting rod and a pluralityof relatively low cost suitably fitted demountable curler tubes of different cross sectional diameters. The curler tubes herein provided have continuous outer curved surfaces which are free from humps, gaps or other discontinuities which -.mar the appearance of curls.

' Among other advantages the means herein provided for mounting the various sized curler tubes onthe heat emitting rod permit theoperator to interchange the various tubes of different sizes or contours rapidly and with ease, thereby conserving the hair stylists time as well as that of his client. 2

This is a continuation-in-part of my application Serial Number 177,320, filed March 5, 1962, now abandoned.
